To aZZjw/wm t may camerati y Y Be it `known. tha-tf1,- JAMES VCWEN, ya. leitizenlot the United States, and resident-ot` Edgeley, in the county'of La Monre and State of North Dal ota,' have invented a new and useful ,Improvement inWVrenClies,` of whichthefollowing' is. aspeoioation.'

invention relates to ivrenehes and has` torits obieetrto .provide a wrenehjhavlng ey device for forcing' the ij awe of said Wrench together to securelyiclamp orvgriplthe object toV be held thereby.

A still further( object 1s to provide adjust said VWrench by means: of. -which'thejavvs ofthe Wrench Can be'spread 'ingV means for 'apart to any desi-red distance required so that the' si'ie 'ofi the object tube damped may' be variedatV willfan'd thei-r degree,y of pressiire appliedfto the-.sarne `-may-.be correspondingly varied.: i.

ln carrying outiny objects l provide 'a shank formed' at Vonevend With a 'j mv' and. at

fslida'bly mounted an operating' headandl a movable body. These two members are-connected together by adjnetingmeans andthe said head iis provided' WithinJ leveribv means of which theV saine together ivithsaidjhea-d may be slide'd upon:v said' shank.; The full objects and advantage"s lotv my invention ivill appear in Connection vvith the detailed description' thereot1 andere partie@V ularly vpointed f ln the drawings illnstrat'ng'the-applieae.

lever 25 is raised I provide a device best 'shown in Figure 2.Y In this0 ligure ittwill be noted that a portion of shank l within the head l is recessed as indicated at 33 to providea space between the saiddhead andv shank. This recess provides a shoulder 34: on the shank l0. A similar shoulder 35 Vis formed on head which is positioned Vopposite t-heshoulder 34. Byplacing a comL pression coil spring 36 within the recess 33 the same maybemade to-engage the shoul-V ders 34 and-35 and tocause thehead l5 to be always forced .towards the lug 3l. -Vith thisy construction yitV can 'readily be` seen that the head l5 moves away from jaw 1l. 'When lever 25 is raisedthe jawsfbecome automatically spread the maximum. amount for any particular setting of the adjusting `screw 17. j

I found with my invention that the same canbe made to rigidly clamp anyobject to be rotated so that the Wrench may be used for unscrewing pipesor battered nuts and bolts to whichthe ordinary wrench couldnot be applied. In addition the wrench when once applied to the nut or pipe remains in position until the operating mechanism has been released so that the usei1 may remove his hands from t-he wrench without the same becoming disengaged thereby. eliminating the necessity of resetting the wrench.`

^ With theparts as 'arranged micrometric adju'stmentcal .be secured so that the wrench can be utilized -to grip upon any surface desired. In certain instances the Wrench when required'zan be used as a vise, thel "to uses 4 I within the scoperof the followingiclaims.

In accordance `with the patent statutesI have described the principles of operation of my invention together `,with the apparatus which Ifnow consider to represent the ,best n embodiment-thereof, butI desire to haveit understood that the construction shownyis only be carried out by other meansand `applied other? than those above set forth Iclaimi- Y f .1w-A. wrench comprising a shank, `a `fixed jawsecured thereto, Va movable jaw mounted upon said shank, atmovable head mounted on said shankadjacent'said jaw, adjusting means positioned` between said movable head f andsaid movable aw, a lever pivoted to said movable head, saidV lever havingan opening extending .through the same formed with a shoulder and a lug having a cam-face issu- 1 ing outwardly fromsaidshank'and adapted to engage said shoulderto forcesaid head and jaw inwardly upon movement of said lever..
